The arc described by a motorcycle's tires as it corners. On a racetrack, the proper line through any corner is determined by a number of factors: Surviveability, best setup for the next corner, best corner exit speed, and preventing other racers from passing, usually in that order. (Racing is stressful and bad decisions get made. That's racing.)

"There's a few lines that work through that combination of corners, choose one that has you sacrifice the entry to the first so you can get a good drive on the exit of the second"
